Strip clip



March 10, 1936. R. KINGSLEY STRIP CLIP Filed Sept. 6, 1954 ATTOR NEYPatented Mar. 10, 1936 v UNITED STATES PATENT OFFICE 2 Claims.

The invention relates to a strip clip and more especially to a spoolclamp for locking strips to spools, such as film strips, etc.

The primary object of the invention is the provision of a clip or clampof this character, wherein strips of cloth, paper, thread, string orother flexible material or composition adapted to be wound on and from aspool can be firmly and securely attached to the latter and is readilyand easily detachable therefrom, the clip or clamp being of novelconstruction and usuable primarily for the fastening of strip films tospools Within cameras.

Another object of the invention is the provision of a clip or clamp ofthis character, wherein the same when attaching the end of a strip to aspool will prevent slippage of such strip or the accidental release ofthe strip from the spool, the strip at one end being readily attached tothe spool with dispatch and firmly held for winding thereon or unwindingtherefrom.

A further object of the invention is the provision of a clip or clamp ofthis character which is extremely simple in construction, thoroughlyreliable and effective for the purposes thereof, strong, durable, andinexpensive to manufacture.

With these and other objects in View, the invention consists in thefeatures of construction, combination and arrangement of parts as willbe hereinafter more fully desccribed in detail, illustrated in theaccompanying drawing, which discloses the preferred embodiment of theinvention, and pointed out in the claims hereunto appended.

In the accompanying drawing:

Figure 1 is a fragmentary plan view of a spool and film strip, showingthe latter attached to the spool by the clamp or clip constructed inaccordance with the invention.

Figure 2 is a fragmentary perspective view.

Figure 3 is a detail perspective view of the clip removed from thespool.

Similar reference characters indicate correspo'nding parts throughoutthe several views in the drawing.

Referring to the drawing in detail, A desighates generally a portion ofa strip of material, for example, a strip film, and B a spool upon whichthe strip is adapted to be wound or unwound therefrom. This spool, asusual, has the end circular guide pieces 5, preferably made from metal,although they may be otherwise formed, for the guiding of the strip inthe winding and unwinding operation.

Provided in the spool B is an elongated slot 6 which extendslongitudinally thereof for a distance of its length and is centered withrespect thereto, the said slot being adapted to open through the spool Bat diametrically opposite points thereof, while the strip A at theattaching end has the outwardly tapered tab terminal I which is threadedthrough the slot 6 in the spool in a manner as is clearly shown inFigures 1 and 2 of the drawing.

The clip or clamp is. in the form of a halfcylindrical body 8,preferably made from inherent resilient material, and has at oppositeends the retaining tongues or ears 9. This body 8 is adapted to besprung into position upon the spool B, so'that the tongues 9 willresiliently embrace such spool for rotatable connection of the bodytherewith. The body "I is preferably of the length of the spool betweenthe end pieces 5 so as to avoid any displacement of the said bodylongitudinally upon the spool. It will be apparent that when the body Iis turned upon the spool to one position the slot 6 will be uncovered sothat the tube 1 can be threaded through such slot with its can bereadily and conveniently wound upon and unwound from the spool in theservicing thereof.

What is claimed is: 1. The combination with a spool having a slotextending transversely therethrough and of less length than said spool,of a springy half cylindrical shaped body frictionally gripping saidspool and embracing the same throughout the length of said spool andturnable about such spool for the fastening of a strip when passedthrough the slot to have the strip at its free end lie between the spooland said body, the said body being cut away between its ends to providea clearance for the free end of said strip.

2. A clip or clamp of the kind described, comprising an inherentlyresilient body of a formation to partially embrace a spool for theclamping of a strip between it and the said spool, the body being of asubstantially half cylindrical shape and cut into at opposite edgesbetween the ends thereof to provide end tongues on said body spaced fromand at opposite sides of its transverse axis and of a length to extendaround the spool for a greater portion of its diameter for frictionallyretaining the body in embracing relation to the spool for turningmovement thereon.
